192,010, dated June 12, 1877 application filed May 3, 1877.

To all whom it may concern:

Be it known that we, ROBT. M. RICE and FRANCIS M. GORTNER, of Keota, inthe county of Keokuk, and in the State of Iowa, have invented certainnew and useful Improvements in Feed-Steamers; and do hereby declare thatthe following is a full, clear, and exact description thereof, referencebeing had to the accompanying drawing and to the letters of referencemarked thereon, making a part of this specification.

The nature of our invention consists in the construction and arrangementof a feedsteamer, as will be hereinafter more fully set forth.

In order to enable others skilled in the art to which our inventionappertains to make and use the same, we will now proceed to describe itsconstruction and operation, referring to the annexed drawing, in which-Figure 1 is a plan View of our feed-steamer, and Fig. 2 is a "erticalsection of the same.

A represents an ordinary water-tight barrel, or similar vessel, withinwhich the furnace is placed.

The furnace B is circular in form, and has a conical top, 0, from theapex of which the smoke-pipe D extends up through the top of the barrel.From one side of the furnace extends a flue, G, through the side of thebarre], and in the end of said flue is a hinged door, E, with damper onfor regulating the draft.

In connection with this we also use a damper, I), in the smoke-pipe D,by the use of which the heat may be retained in the furnace.

The smoke'pipe D is surrounded by a sleeve or larger pipe, H, the lowerend of which reaches down to the conical top 0 of the furnace, and formsa cold-air chamber, 01, around the smoke-pipe. The upper end of thesleeve H is attached to the inner edge of an annular plate, I, securedto the top of the barrel, and the smoke-pipe D passes up through thecentral orifice in the same, and is attached to a g flanged four-armedspider, J, the arms of which lie on top of the plate I and are fastenedto the top of the barrel, as shown.

The cold-air chamber d, formed by the sleeve H around the smoke-pipe,prevents the melting of the solder, which is often liable to occurotherwise.

The parts I and J are so arranged that, with the flue Gr, they willsupport the furnace/a short distance, say two inches (more or less)above the bottom of the barrel, so that the water will have free accessto every part of the surface of the furnace; and the top of the furnacebeing conical, as shown, increases the heating-surface.

A grate for burning coal may be arranged in the furnace B.

In the top of the barrel is the waterinlct of hose to conduct the steamto any point desired; and, further, there is a safety-valve, consistingof a spring, S, with pad 1;, covering a vent or escape-hole in the topof the barrel.

Having thus fully described our invention, what we claim as new, anddesire to secure by Letters Patent, is-

the furnace B with flue G, having damper a and conical top 0, thesmoke-pipe D having damper b, surrounding sleeve H, and cold-air chamber01 between the sleeve and. smokepipe, substantially as and for thepurposes herein set forth.

2. The combination, with the furnace B U, of the sleeve H, annular plateI, smoke-pipe D, and flanged four-armed spider J substantially as andfor the purposes herein set forth.

In testimony that we claim the foregoing we have hereunto set our handsthis 17th day of April, 1877.
